Can soul experience vision, sound, touch without a body?
No, this not possible because what is called as experience is nothing more than the sense and mind validation.
Suppose if Anesthesia is given to a person for going to deep sleep, and after he wakes up than what is his experience ? Deep Sleep state has no experience, as the senses are not there to register anything. It is the absence of senses & mind.
Body ( senses & mind) are the mandatory requirements for any experience.
After death, does soul travels from earth to various lokas?
No, this is not possible. Body has qualities of seeing & registering the same, but a soul who is formless it cannot be a seer of anything. Soul doesn’t haves eyes, eyes is a quality of physical body.
There is a journey after the death of body, it is belief. It will never happen, because the Atman ( soul ) has been mentioned as Location-less, timeless & formless entity in the Upanishads.
For a journey to happen, you need to be a form, which is located at a particular place within a certain time. They all are not applicable for the Soul.
